In this embodiment, the workpiece 100 is fixed on the clamping seat 1. Since the clamping seat 1 is arranged on the Y-axis rotation module 21, and the Y-axis rotation module 21 is arranged on the X-axis rotation module 22, the workpiece 100 can be rotated around the Y-axis and the X-axis respectively under the drive of the rotation system 2; since the glue cylinder 41 is arranged on the Z-axis translation module, and the Z-axis translation module is arranged on the X-axis translation module, the dispensing system 4 can be moved along the Z-axis and the X-axis respectively under the drive of the translation system 3.

[0038] Specifically, the screw valve 42 is a kind of existing dispensing valve in the art, which is provided with a stator and a screw that mesh with each other, and the screw is driven by a servo motor to rotate to realize the push flow of glue. Its specific structure and principle are not described here. In this embodiment, compared with the dispensing valve commonly used in the dispensing machine, the screw valve 42 driven by the servo motor can achieve a single minimum dispensing amount of 0.001g, accurate measurement, uniform glue discharge, and can effectively avoid glue overflow, thereby greatly improving the dispensing quality.

[0040] Specifically, Figure 1 and Figure 2 As shown, the five-axis linkage glue dispensing machine also includes a gantry 6, which is arranged on the mounting platform 5 on both sides of the Y-axis translation module, and the X-axis translation module is arranged on the gantry 6. In this embodiment, the gantry 6 is arranged on the mounting platform 5, and the Y-axis translation module is arranged between the vertical beams on both sides of the gantry 6; the gantry 6 improves the installation strength and stability of the X-axis translation module, and saves the installation space on the mounting platform 5, so that the glue dispensing system 4 on the X-axis translation module can perform glue dispensing on the workpiece 100 from above.

[0041] Specifically, the X-axis translation module includes a first drive motor, a lead screw, a guide rail and a slider. The guide rail is arranged on the gantry 6 along the X-axis. The lead screw is connected to the drive motor in parallel with the guide rail and the drive motor can drive the lead screw to rotate; the lead screw is inserted into the slider and matched with the slider thread, the slider is embedded in the guide rail and can slide along the guide rail, and the Z-axis translation module is arranged on the slider. In this embodiment, the X-axis translation module is a lead screw guide device commonly used in the art. When the first drive motor drives the lead screw to rotate, the slider matched with the lead screw thread will drive the Z-axis translation module thereon to move along the guide rail; specifically, the Z-axis translation module and the Y-axis translation module have the same structure and working principle as the X-axis translation module. It can be understood that the Z-axis translation module, the Y-axis translation module and the X-axis translation module can also be pushed by a telescopic cylinder or other structure capable of horizontal displacement to translate on the guide rail, which is not limited here.

[0042] Specifically, Figure 1 and Figure 2 As shown, the X-axis rotation module 22 includes a second drive motor, a rotation shaft and a fixed plate, the second drive motor is arranged on the Y-axis translation module; the rotation shaft is connected to the second drive motor and the second drive motor can drive the rotation shaft to rotate, the fixed plate is arranged on the rotation shaft, and the Y-axis rotation module 21 is arranged on the fixed plate. In this embodiment, the second drive motor can drive the rotation shaft to rotate, thereby driving the Y-axis rotation module 21 on the fixed plate and the workpiece 100 on the Y-axis rotation module 21 to rotate counterclockwise or clockwise around the X-axis; specifically, the structure and working principle of the Y-axis rotation module 21 and the X-axis rotation module 22 are the same.

[0043] Specifically, Figure 1 and Figure 2 As shown, the five-axis linkage glue dispensing machine also includes a support seat 8, which is arranged on the Y-axis translation module, the second drive motor is fixed on the support seat 8, and the rotation shaft is passed through the support seat 8 and rotates with the support seat 8.

[0044] Furthermore, if Figure 1As shown, the five-axis linkage glue dispensing machine also includes an oil seal cup 7, in which oil for immersing the needle 43 is contained. In this embodiment, the oil seal cup 7 contains oil. When the glue dispensing operation of a workpiece 100 is completed and the next workpiece 100 is replaced, the translation system 3 drives the needle 43 to extend into the oil in the oil seal cup 7, thereby achieving the sealing of the needle 43 and preventing the glue in the needle 43 from oxidizing and affecting subsequent use. In addition, a test glue copper wire is also provided on the mounting platform 5. When the next workpiece 100 is replaced and before the glue dispensing is started, the needle 43 first hits a small amount of glue on the copper wire and scrapes it off, and then the workpiece 100 is glued to ensure that the glue coated on the workpiece 100 is qualified glue without impurities at the end of the needle 43.
